fl'b all whom it may concern;

Be it known that I, Wnmmn B. FULTON, a citizen of the United States, residing at Middletown, Butler county, Ohio, have invented certain new and useful lmprove-' ments in Chimney-Building Accessories, of

. which the following is a specification.

This invention relates to accessories for I facilitating the construction of chimneys in freezing weather and has been devised with special reference to the building of chimneys of concrete, v

lhe invention will be readily understood from the following description taken in connection with the accompanying drawing, which is a side elevation part vertical diametrical section of an exemplification of the improved accessories at the progressing upper portion of a chimney being constructed of concrete.

In the drawing I 1, indicates the upper end of the completed portion of the chimney:

2, the exterior form or mold: I 3, the interior form or mold:

4:, concrete being filled in on top ct the completed work between the inner and outer forms:

5, trestlework extending from the base of the chimney upwardly and added to upwardly as the work progresses:

6, the cathead supported by the trestlework: 1

7, a skeleton bracket-ring supported by the trestlework in position above the forms:

8, suspenders connecting the forms with the ring: and

9, the catfalls illustrated rudimentally. All of the parts thus far referred to may be of usual construction and subject to any usual appropriate modifications. In operation the forms are supported from the cathea the lower ortions. of the forms en-. pleted hardened work, and

gaging the com I green concrete is filled Into the mold space and allowed to set, When the concrete is properly hard then the molds are elevated so as to form a new mold-space above the work which has hardened, the lower por fl trap or tank or waste.

tion of the forms still engaging the finished cathead will have been elevated and arranged for support by means of properly added trestlework. All of this is as usual Specification of Letters Eatent.

and the improvements to be described are deslgned to provide for continuing the work in freezing weather, of weather so severely cold as to render reliable concretlng impracticable under ordinary conditions of procedure, I

Proceeding with the drawing-:

10, indicates 5a helical coil of pipe surrounding the outer form, the coil having at leastthe vertical height of the forms, the coil beingformed ofsegments ofpipe suitably united by unions to facilitate erectioni 11, a curtain-ring, supported above the molds, this curtain-ring being preferably formed or-carried by'bracketringfl, the curtain-ring, however formed and su ported, being larger-in diameter than the pipe-coil:

12, a curtainrring at the base or" the coil and preferably supported by brackets from the outer form: I

13, .an 'inclosin curtain of an suitable material, surroun ing the coil and hanging from the upper curtain-ring and projecting below the lower curtain-ring; A

14, a girdle of any suitable material and construction, surrounding the lower portion of the curtain and drawing and holdin the base of the curtain against the comp eted portion of the chimney below the molds:

15, a steam-supply pipe, preferably a hose,

1 extending up through the lnterior of the chimney and connected with the coil and adapted for connection at its base with a boiler or other source of steam-supply:

16, a throttle-valve in the supply-pipe:

vided, if desire in the supply-pipe:

17, a reducin valve which may be pro 18, a steam gage whichmay be provided,

if desired, inthe supply-pipe.

19, a recording thermometerwhich may be provided, if desired, at some appropriate point in the near nei hborhood. of the mold erable location for this thermometer being in the. space between the'ourta n and the outer'form: and

space being 'filled with concrete, the prei= Q ,100 20, thedrain-pipeleading from the coil,

the -discharge end of this drain-pipe being adapted for. connection with any suit i,e

By means of he steam coil, the region of molding may be kept at proper tempera ture, the curtain' protecting the co l from the general atmosphere and from winds. The

the annular space formed within the curtain be closed to prevent currents of airupward through the space. This inclosure may be effected by any suitable flooring for the space, as by extending the curtain inwardly to the chimney. In practice, and in the illustrated exemplification, the curtain is of textile fabric, as canvas, with its skirt gathered inwardly and joined to the chimney by the girdle 14. It is desirable that the curtain, regardless of the material of which it is constructed, extend below the outer form so as to give protection to that portion of the completed work immediately below the outer form. When a section of the work has hardened and the forms have been elevated to furnish the mold space for further worK,

the completed work off which the forms have been raised may contain such an amount of moisture that immediate .ex-

-posure to the weather is undesirable. It is manifest that the base of the curtain may extend to far below the outer form as to encompass all of the new work representing the last preceding molding operation. 4

The reducing valve, if employed, permits of an insured definite pressure in thecoil reduced from an excessive pressure in the supply-pipe, If a chimney-building contract specifies that the concreting be donewithin certain limits of temperature, the recording thermometer, which should be kept on the windward side of the structure, will serve to show the temperatures whichhave been prevailing at all times during the conjillllClIlOIl- While an excessive pressure of steam coming through the supply-pipe may be reduced by means of the throttle valve before going to the coil, and while it may be reduced automatically by the reducing valve, if employed, it is my preference that the control of the steam to the coil be under the influence of the temperature at the molding region instead of under the steam pressure, and this is accomplished by-employing a reducing valve of the thermostatic type in which the flow of the steam past the, valve is controlled by the temperature in the neighborhood of the valve.

While the invention has been devised with special reference to the building of concrete chimneys, it is available in the building of analogous concrete vertical structures such,
